NCT03624257

Brief Summary

A clinical trial comparing laser treatment and conventional mucosal flap surgery for treatment of peri-implantitis. The main aim of the study is to evaluate if treatment of peri-implantitis with a novel blue laser (445 nm) combined with scaling and root planning (SRP) is clinically comparable to conventional mucosal flap surgery in terms of pocket probing depth reduction.

Outcome Measures

Primary Outcomes (1)

  • Mean change from baseline in Pocket probing depth (PPD) at 6 months after treatment.

    Pocket probing depth (PPD) will be measured by a 1 mm graded pocket probe from the bottom of the peri-implant pocket to the marginal mucosa and will be registered on 4 surfaces surrounding the implant.

    At baseline and 6 months post treatment

Secondary Outcomes (9)

  • Mean change from baseline in Plaque index (PI) at 6 months after treatment.

    At baseline and 6 months post treatment

  • Mean change from baseline in Bleeding on probing (BOP) at 6 months after treatment.

    At baseline and 6 months post treatment

  • Mean change from baseline in Recession of the marginal mucosa at 6 months after treatment.

    At baseline and 6 months post treatment

  • Mean change from baseline in Presence of suppuration at 6 months after treatment.

    At baseline and 6 months post treatment

  • Mean change from baseline in Marginal bone level on radiographs at 6 months after treatment.

    At baseline and 6 months post treatment

  • +4 more secondary outcomes

Study Arms (2)

Scaling and root planning + Laser treatment

EXPERIMENTAL
Device: Laser treatment

Mucosal flap surgery

ACTIVE COMPARATOR
Procedure: Mucosal flap surgery

Interventions

The participants in the laser group are treated by a combination of scaling and root planning (SRP) and 445 nm diode laser. The peri-implant pocket will be radiated with the 445 nm laser, removing bacteria, diseased epithelium and granulation tissue. The Power setting on the laser will be 0.7 W continuous wave and will be used at maximum 20 s Before cooling water is applied. Total treatment time will vary with the depth of the pocket and size of the surrounding bone crater.

Scaling and root planning + Laser treatment

The participants will receive a conventional peri-implant mucosal flap surgery of affected implants, in combination with scaling and root planning (SRP), and return after 7-10 days for suture removal. The surgery is a well-established treatment of peri-implantitis.
